Infineon公司的CoolSET™-Q1系列(ICE2QRxx80Z)是第一代准谐准集成功率集成电路,其有源突发模式可使无负载时达到最低的待机功耗小于100mW,数字频率的降低有更好的整个系统效率,集成了带起动单元的800V雪崩强健的CoolMOS™,无铅镀铅,无卤模塑料以及RoHS兼容,VCC过压和欠压保护的自动重起模式,超温保护的自动重起模式,用于可调整输出过压保护和变压器短路绕组保护的闩锁模式,主要用在适配器/充电器,蓝光/DVD播放器,机顶盒和数字像框,以及服务器,PC,打印机,TV,家庭影院/音频系统,白色家电等.本文介绍了ICE2QR1080G产品亮点和主要特性,框图和应用电路,简化多输出反激转换器框图,60W演示板DEMO_5QSAG_60W1主要特性,电路图,材料清单和PCB设计图.

The CoolSET™-Q1 series (ICE2QRxx80Z) is the first generation of quasi-resonant integarted power ICs. It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD Combo, Blue-ray DVD, set top box, etc. Operting the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on the BiCMOS technology, the CoolSET™-Q1 series has a wide operation range (up to 25 V) of IC power supply and lower power consumption. It also offers many advantages such as: a quasi-resonant operation till very low load increasing the average system efficiency compared to other conventional solutions; the Active Burst Mode operation enables ultra-low power consumption at standby mode with small and contro..
